Pattern Searching
You are able to search for any data pattern up to
32 bytes in length while in the Memory Window. To bring up the search dialog box
pressing the ALT_S key sequence or from the menu.
-
Enter the pattern you want to find on the first
field. If you want to enter a hexadecimal value then you can use the "\x"
escape sequence followed by the hexadecimal number you want to search for.
-
You can instruct SI_SCOPE to start
its search from the current screen or from the top of it's heap with the
"Perform Global Search" option. If you enable this option
SI_SCOPE will search the entire memory buffer for a match on
your data. With the option off the search will take place starting at the
position of the upper left character on the screen to the end of the buffer.
-
You can search for a data pattern on both ports or
just one port. This is useful if both devices send a specific pattern and you
want to find where one of them sent it. For example when reviewing a session
you might want to find the spot where the DTE device sent an ACK to the DCE
device. Since most communication protocols allow an ACK from either device,
there can be an unbearable number of them in a session. By limiting the search
to the DTE port you can speed up the time it takes to find the
pattern.
If the pattern is found it is shown in highlight with
the actions bar updated to reflect where you are in the session. If the pattern
is not found SI_SCOPE beeps and displays unsuccessful
match dialog.
Signal Searching
You can also search for recorded signal events if you
have the signal capture option on (see
"Viewing RS232 Signal Changes). To search for a signal event choose the "Search Memory
Window" option from the "Functions" menu.
